Zhang Yu's soul enters the body of a man with the same name. He discovers that the original owner worked tirelessly gathering seafood to earn money, doing all the hard work for his family and handing over every penny of his savings. Unfortunately, his parents favor his younger brother, Zhang Yang, and gave the entire family savings to the wastrel, who squandered all the money Zhang Yu had earned. He even looked down on his older brother, believing Zhang Yu was born to be a slave in the family. The Zhang Yu who has taken over the body decides to stop letting his family bleed him dry and cuts ties with them. Amid their mockery, he leaves on his own in a broken-down wooden boat and begins his life gathering seafood. Exhausted and hungry, Zhang Yu catches a fish and gains an evolution point. He starts upgrading his shabby boat, and the more fish he catches, the more evolution points he can earn. As his catches grow, his fishing boat keeps evolving, until it becomes a deep-sea aircraft carrier. Wherever it goes, the waters are my fishing grounds!
